Abstract

The invention provides a mobile terminal. The edges of cooling fins are designed to be a plurality of edges which are connected end to end and are not located on the same straight line, each edge forms a certain angle, therefore, the radiation direction of the interference signal is relatively scattered, gain enhancement caused by radiation of all interference signals towards one direction is avoided, and meanwhile, the length of each edge is smaller than 1 / 4 wavelength of an interference signal generated by the terminal main body, so that the edge of the cooling fin is not enough to radiate enough interference signal wavelength, the radiation of the interference signal is weakened, and the interference of the cooling fin on the mobile phone antenna is avoided to the greatest extent.

Description

technical field [0001] The present application relates to the technical field of terminals, and in particular to a mobile terminal. Background technique [0002] At present, the main board of the mobile terminal is usually equipped with a high-heat module. When the high-heat module is working, a large current will flow through it, which will generate a high interference signal to the antenna. Under normal circumstances, the high interference signal will directly radiate outside the mobile terminal. , will not cause interference to the antenna of the mobile terminal. However, because graphite sheets made of graphite materials are usually pasted on the casing of existing mobile terminals to dissipate heat from the mobile terminals, and considering that graphite sheets are conductors, interference signals will be disturbed during the process of radiating outward. It will be blocked by the graphite sheet and reflected back to the main board, and then radiated again after being ...
